Traveling through ancient times: Savages are hungry for food

in the afternoon.

Lei arranged 20 efficient tribesmen to help Sang Tian.

If you want to make charcoal, the first thing you need to do is build a stove.

If you build a bigger stove, you can burn more charcoal at one time, and you also need to burn pottery pots.

By building a fireplace for burning charcoal, you can also burn pots at the same time. The temperature of charcoal is 200 to 300 degrees higher than that of an open flame, and can reach over 1000 degrees in a closed space.

……

Sang Tian chose the leftmost side of the square as the place to build the stove.

This area is flat, dry, and well-ventilated, making it ideal for building boilers.

And there are no flammable materials around, which is safer and can prevent fire caused by burning charcoal.

Sang Tian first determined the shape and size of the boiler.

Most furnace walls are semi-elliptical or square.

Sang Tian firmly adopted the square shape.

As for the size, it is one meter high and two meters wide.

……

But what we need to do now is to make earth bricks!

Sang Tian brought a few people to the river where Yong moved the big stone pot.

There is a large area of yellow mud clay here.

Strong water retention and plasticity.

However, Sang Tian felt that using clay to make bricks was a bit too extravagant, so he chose to mix ordinary soil and clay.

Sprinkle some hay segments to increase firmness.

Because it was a furnace, Sang Tian wanted it to be sturdy. But if he was going to build a house with earth, he could just use regular earth. Otherwise, it would be too extravagant!

In agricultural terms, raw soil is soil that has not been cultivated. Soil in farmland where crops are often grown is cultivated soil.

……

Following Sang Tian's instructions, the tribesmen dug yellow mud from the bamboo cart, and Sang Tian made a mold with the bamboo board.

The size of the mold is about the same as the size of the brick, and this is the size used for earth bricks.

The female mixes the dug yellow mud with raw soil in a one-to-one ratio.

And these. Raw soil is turned into wet soil by adding appropriate amount of water.

Sang Tian put the mixed soil into the mold and pressed it firmly.

Just pressing with your hands is not enough!

If you want the earthen bricks to be strong and fire-resistant, you need to hammer them thousands of times.

The strongest males present were responsible for this task, using wooden stakes to hit the clay in the mold.

If you are building an earthen house, the bricks must be dried naturally.

But now we are building a kiln, so wet bricks are fine. We can also let it dry naturally after we build it.

……

An hour later, enough bricks were thrown to build the furnace walls.

Following Sang Tian's instructions, the school dug some fresh clay and pulled it onto a bamboo cart.

The group pulled the clay and beaten bricks to the construction site selected by Sang Tian.

……

Sang Tian removed the earthen bricks from the mold, which were already very hard.

The earthen bricks were placed in a square shape, two pieces together, according to the previously determined size frame.

The gap between the two bricks was sealed with clay.

Then, apply a layer of clay on the circle of bricks, and then overlap the bricks...

Repeat this process.

When they were at about the same height, Sang Tian took over personally.

A furnace door was left.

Use several thicker and longer pieces of firewood, place them vertically on the bricks at the bottom of the front, and then place bricks on top of the firewood.

The same goes for the top of the furnace. Use wooden stakes to support it, and then build a layer of earth bricks on top. But a ventilation device must be left. Sang Tian left a chimney on the top.

Insert a piece of bamboo into the specially left gap, and then fill and seal the gap with clay.

This will ensure that the wood burns thoroughly.

The males imitated Sang Tian and built the earthen bricks tightly. They strictly followed Sang Tian's example to ensure that the gaps between the bricks were filled evenly.

To improve the sealing of the boiler, so as to ensure that heat will not be lost.

At the bottom of the boiler, leave a furnace to place wood and clay pots.

An hour later, a furnace was completed.

Don't rush to burn it now. After all, the beams inside are supported by firewood, and if the support is burned, the support will also be burned.

It has just been built and is not yet stable. If the supporting wood is destroyed, it may collapse.

So leave it to dry.

Dry it in the sun for half a day today and then overnight.

Tomorrow we will start burning charcoal!

……

After all this, everyone was covered in mud. I thought we had just rolled around in it...

There was also dried mud on Sang Tian's hair.

I couldn't stand it anymore, so I went back to the cave to boil some water and take a bath.

……

Five o'clock in the afternoon...

The primitive hunting team returned with a full load.

"Cang, look! What's that thing on the edge of the square? It's just a square lump!"

Cang followed Yong's gaze.

There is a taller and wider mound of earth over there.

But it is very different from ordinary soil.

It looks very solid, and yellow soil is seeping through the gaps.

And the whole clod of earth looks half dry...

"You don't know this, do you? This is made by the people of Sangdai! They say you can use it to burn wood without smoke. Use it for heating in the snowy season!"

"What? You can burn wood without producing smoke!

Then our snow season will be much better!"

"What's that? Sang said she would make something else, so we can put down the animal skin curtain!

I can’t even imagine how warm it will be!”

Yong jumped up excitedly and hugged Cang's arm!

"Cang! Did you hear that? He said we can lower the curtains during the snow season! And there's no cigarette! Ahhhhh! I can't even imagine how cheerful and masculine I'll be during the snow season this year!"

"I heard you! You're making so much noise that my ears are about to get calluses!"

……

Cang was actually not very surprised.

Just happy for the change.

Because he knew that any miracle happening to Sang was a normal thing.

Everything she knows is amazing.

He was happy for the tribe and proud of San...

Only...

He would doubt whether he was worthy of Sang?
